Abstract: 567,388. Making hollow - ware. SOC. ANON. POUR L'INDUSTRIE DE L'ALUMINIUM. Aug. 13, 1943, No. 13175. Convention date, Nov. 25, 1942. [Classes 83 (ii) and 83 (iv)] Forging; extruding.-A hollow body of non- ferrous metal is made by forcing a mandrel 3 into a blank 6 while in a matrix 1, having its bottom closed by a die 5, shaped to give the desired external form to the blank, the thick walled hollow body so formed being then extruded through an open die 8, Fig. 3, which is fitted to the matrix in place of the closed die. The blank 6 is preferably wrought or extruded. It may be of aluminium alloy and have a mandrel-centring hole drilled a short distance into it. The die 5 may have a removable core so that when this has been withdrawn it forms the open die. The extruded body 16 may have its open end closed in and fitted with a closure to form a high-pressure vessel. It may also be heat treated, drawn, straightened, polished, &c. The Specification as open to inspection under Sect. 91 comprises also the closing of the bore in the mandrel 3, shown in dotted lines, by means of a plug which prevents the metal 6 from entering, this plug being unseated by air pressure in the second stage. This subjectmatter does not appear in the Specification as accepted.
Patent GB-817139-A (GB)
Title: Preparation of 5-hydroxymethyl 2-furfural
IPC: C07D307/46
Filed: 1956-04-30
Abstract: 5-Hydroxymethyl-2-furfural is produced by heating an aqueous solution of a keto-hexose sugar at a temperature between 125 DEG  and 225 DEG C. in the presence of an unsubstituted saturated aliphatic monohydric alcohol, preferably having from 1 to 5 carbon atoms in the molecule, the molar ratio of the alcohol to water in the solution being between 0.1 and 0.4.  Preferably a catalyst is used.  An acidic catalyst, i.e. an inorganic or organic acid or a substance which generates an inorganic or organic acid radical is used, e.g. hydrochloric acid, hydrobromic acid, phosphoric acid, zinc chloride and aluminium chloride.  The preferred catalysts are strong mineral acids, especially sulphuric acid.  In some cases it may be desirable to stop the reaction before the maximum yield of 5-hydroxy methyl-2-furfural is obtained.  In the examples: (a) levulose, dilute sulphuric acid and n-butyl alcohol are heated together at 170 DEG  C.; (b) sucrose, dilute sulphuric acid and n-butyl alcohol are heated together at 150 DEG  C. in two stages; (c) crude black-strap molasses is diluted with water and de-ashed by passage over a column of cation exchange resin; this solution is mixed with butanol and heated at 150 DEG  C.; and (d) various mixtures of sucrose, sulphuric acid, n-butyl alcohol and water are heated at 150 DEG  C.  In all cases 5-hydroxymethyl-2-furfural is obtained. Another material which may be used as starting material is inulin from Jerusalem artichoke tubers or chicory.  When sucrose is used as starting material it is rapidly hydrolysed to invert sugar. Specifications 591,858, [Group IV], 600,871 and U.S.A. Specification 2,498,918 are referred to.

Title: Improvements in electrical distribution in alternating current systems
IPC: H02J3/02
Filed: 1921-02-07
Abstract: 179,824. Taylor, A. M. Feb. 7, 1921. Polyphase systems.- A single-phase or a polyphase current is superposed upon the currents of existing three-phase cables by employing transformers having a broken-up delta winding, a broken tee winding or a broken open delta winding. The current from an auxiliary generator AG, Fig. 1, is superposed upon the currents of existing three - phase cables 3PC by connecting the generator AG to the mid-points of the secondary windings S<1>, S<2>, S<3> of a transformer SUT. The superposed current is taken from the mid-points of the primary windings P<1>, P<2>, P' of the transformer SDT and transformed by a transformer TTT. In the arrangement shown in Fig. 2, a two-phase auxiliary generator AG is connected to the three-core cables 3PC through the secondary windings E of a three-phase twophase transformer. The sections of the cable sheathings CS or LS are connected by resistances RR to equalize the potentials on the sections. In a modification, four conductors of the two threephase cables are employed to supply the energy and the remaining two conductors are utilized as returns for the superposed current. Three single-phase transformers are employed and two are connected in parallel on the overloaded side. A further modification is described in which a two-phase current is superposed and a two-phase three-phase transformer is employed at the receiving end. Specifications 151,294 and 158,008 are referred to.

Patent GB-793491-A (GB)
Title: Process of recovering basic antibiotics
IPC: B01J47/00
Filed: 1956-05-02
Abstract: Nitrogen basic antibiotics such as neomycin, streptomycin and streptothricin are recovered from a fermentation broth, or an acid filtrate thereof, by adsorption on a particulate cation exchanger in its amine salt form, and elution therefrom with a dilute mineral acid such as hydrochloric, nitric or sulphuric at pH 1.5 to 4.5.  It is preferred however to elute with mineral acid of pH 4.5 to 6 to remove any alkali or alkaline earth metals before removing the antibiotic by elution at pH 1.5 to 4.  Ion exchange resins deriving their exchange capacity essentially from carboxylic groups, e.g. Alkalex, "Amberlite" IRC-50 (Registered Trade Mark), "Duolite" CS 100 (Registered Trade Mark), "Permutit" H-70 (Registered Trade Mark), and "Wolfatit" C may be used.  The cation exchanger is treated with the organic amine as such, if liquid, or in solution in water or aqueous organic solvent, e.g. aqueous ethanol, in order to be converted to the salt form.  Specified amines are primary, secondary and tertiary aliphatic amines such as methylamine, diethylamine and triethylamine, the primary, secondary and tertiary cycloaliphatic amines, e.g. cyclobutylamine; the primary, secondary and tertiary araliphatic amines, e.g. benzylamine; and heterocyclic amines, e.g. piperidine, pyrrolidine morpholine and their alkyl substituted derivatives. Preferably the amine is such that its salt with the eluting acid has a different solubility from the salt of the antibiotic with the eluting acid.  The process may be batch or continuous.  It is preferred to use the acid filtrate obtained by acidifying the broth to a pH of 1.5 to 3 with mineral acid and filtering with a filter aid.  The pH is then adjusted to pH 5 to 9.5, and preferably 7 to 8.5 with an amine.  If desired, a sequestering agent for alkaline earth cations, ethylenediamine tetraacetic acid may be added to the acid or neutralized filtrate before the adsorption step.  After elution, the eluate is adjusted to pH 5 to 7 by means of an anion exchange resin, e.g. "Amberlite" IR-4B, concentrated if desired, and the antibiotic precipitated by means of a non-solvent in which the salt of the amine with the eluting acid is soluble.  Such solvents are the water-miscible alcohols, e.g. methanol and ethanol; the watermiscible ketones, e.g. acetone; the watermiscible ethers, e.g. dioxane; water-miscible nitriles, e.g. acetonitrile and the water-miscible amides, e.g. dimethyl formamide.  The antibiotic salt may be vacuum or freeze dried or converted to the free base.

Title: Improvements in or relating to spring motors
IPC: F03G1/00
Filed: 1963-04-05
Abstract: 970,769. Spring mechanisms. TENSATOR Ltd. April 5, 1963 [May 21, 1962], No. 13739/63. Heading F2S. A spring motor has on a shaft 14 a concentric and freely rotatable drum 16 on to the outside of which a ribbon driving spring 24 is reverse wound from a supply coil 20 offset from the shaft axis, means being provided to prevent reverse rotation of the coil 20 wound about the shaft and a second driving spring 44 reverse wound inside the drum being connected between the shaft and the drum to cause them to rotate relative to each other. The springs 24 and 44 are non-cumulative force ribbon springs. The shaft 14 carries the drum 16 on bearings 18. The means to prevent reverse rotation comprise a ratchet wheel 48 co-operating with a pawl 50 and torsion spring 53. Stops 26 and 36 with springs 32 and 42 co-operating with notches 30 and 40 are provided to prevent overwind of the spring 24 in either direction (see Figs. 1 and 2). The whole assembly is mounted in a case 10 with cover 12. Winding is effected by rotating the shaft 14 in a clockwise direction (Figs. 1 and 2). After the spring 44 has wound a small amount, the spring 24 will wind and, finally, the remainder of spring 44. When the pawl 50 is released to operate the motor, the drum 16 remains stationary until the torque exerted by the spring 44 falls below that exerted by spring 24, which then coils on to the drum 20 and is followed by a final rotation due to the remaining torque of spring 44 (see Fig. 7). The effect of using pairs of springs with other characteristics is discussed (Figs. 8 to 11, not shown). Specification 789,221 is referred to.
